1. Installing Perl
Running Circos requires Perl to compile its various Code,unix environments by default for Perl, and for Windows users, it is necessary to install them themselves or to verify that they are installed by Perl–v. You can install Strawberry perl or ActiveState perl by cpan the shell to install the module. (See step two for module installation)

################### Second, configure Perl module modules ####################
#################################################################

1. Installing Perl modules: Running Perl requires the following modules to be installed.
Config::general (v2.50 or later)
Font::ttf
Gd
List::moreutils
Math::bezier
Math::round
Math::vecstat
Params::validate
Readonly
Regexp::common
Set::intspan (v1.16 or later)
Text::format

2. Install Module method: (Take GD module for example)
① These module downloads: url: http://search.cpan.org/
② extracted to the Lib directory in the Perl installation directory;
③ Open cmd, enter the module folder under the current Lib folder: CD C:\perl\lib\GD
④ re-enter: Perl makefile.pl
⑤ re-enter: Dmake
⑥ re-enter: Dmake test
⑦ re-enter: Dmake Install

The next module is all configured in a similar way to prevent future runs from going wrong.

1. Enter Example directory: CD C:\circos-0.66\example
2. The first example of debugging: Perl. \bin\circos-conf. \etc\circos.conf
3, debugging a second example: Perl. \bin\circos-conf. \tutorials\2\2\circos.conf
4, debugging a third example: Run this program before you have to create a new directory in the example directory New_output, and then enter the following code
Perl.. \bin\circos-conf. \tutorials\2\2\circos.conf-outputdir. \new_output-outputfile tutorial_image.png
